Abstract
There is provided an electronic conference system, including a display controller that arranges and displays a marker for specifying a display position on a display screen of a display apparatus which placed in a conference room, a unit that obtains information concerning the display position of each marker included in an image capturing range obtained by capturing an image of a portion of the display screen by a conference participant using an information terminal device and that specifies an image capturing region on the display screen based on the information concerning the display position of each marker that is obtained, and a unit that combines image data displayed on the display apparatus at the time of image capturing performed using the information terminal device having an image capturing function with display data, to be displayed in the image capturing region that is specified, to generate a screen image.
Abstract
There is provided an electronic conference system, including a presenter terminal device that displays on a screen of a presenter display in an electronic conference, a conference participant terminal device that receives a screen image displayed on the presenter display and displays the screen image on a screen, a receiving unit that receives the screen image sent from the presenter terminal device, and a storage processing unit that writes a currently displayed screen image in a memory, when a screen image which is different from the currently displayed screen image has not been sent from the presenter terminal device within a predetermined time.
Abstract
A conference terminal for a digital voice conference system comprises a first sound transducer means, which is implemented to generate a microphone signal from an acoustic signal, a second sound transducer means, which is implemented to generate an acoustic signal from a loudspeaker signal, a connecting means, which is implemented to enable a connection between conference terminal and a conference central unit, to receive a composite conference signal from the conference central unit, and a means for echo suppression, which is implemented to combine the microphone signal or a signal derived therefrom in a noise suppression means with a composite conference signal in a listening operation of the conference terminal, such that a loudspeaker signal results, in which the acoustic signal, on which the microphone signal is based, is reduced. Such a conference terminal allows the suppression of a remote own echo and a remote foreign echo, whereby digital wireless voice conference systems can be realized, which ensure high voice quality and noise immunity with minimum wiring effort. |
